Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-1529)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input within the NotificationsDB module. A remote attacker can trick the victim to visit a specially crafted web page, which passes malicious messages to the parent process where the contents is used to double-index into a JavaScript object. As a result, an attacker can perform prototype pollution and execute arbitrary JavaScript code in the privileged parent process.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
2) Code Injection (CVE-ID: CVE-2022-1802)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to prototype pollution in Top-Level Await implementation. A remote attacker can trick the victim to visit a specially crafted website, corrupt the methods of an Array object in JavaScript via prototype pollution and execute arbitrary JavaScript code in a privileged context.
Successful exploitation of the vulnerability may allow an attacker to compromise the affected system.
3) Spoofing attack (CVE-ID: CVE-2022-1834)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of multiple Braille Pattern Blank space characters, which results in displaying every space character. A remote attacker can spoof the email address of the sender.
4) Information disclosure (CVE-ID: CVE-2022-31736)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when processing HTTP requests. A malicious website can obtain the size of a cross-origin resource that supported Range requests.5) Out-of-bounds write (CVE-ID: CVE-2022-31737)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error in WebGL when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it using the affected software, trigger out-of-bounds write and execute arbitrary code on the target system.
6) Spoofing attack (CVE-ID: CVE-2022-31738)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error when exiting fullscreen mode. A remote attacker can use an iframe to confused the browser about the current state of fullscreen and perform spoofing attack.
7) Path traversal (CVE-ID: CVE-2022-31739)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when saving downloaded files on Windows. A remote attacker can use the "%" character in filename to store data outside the intended directory using Windows environment variables, such as %HOMEPATH% or %APPDATA%.
The vulnerability affects Windows installations only.
8) Buffer overflow (CVE-ID: CVE-2022-31740)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error related to register allocation problem in WASM on arm64. A remote attacker can create a specially crafted webpage, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) Use of Uninitialized Variable (CVE-ID: CVE-2022-31741)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted webpage, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Information disclosure (CVE-ID: CVE-2022-31742)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to an error when handling a large number of allowCredential entries. A remote attacker can trick the victim to visit a specially crafted website, launch a timing attack and detect the difference between invalid key handles and cross-origin key handles. Successful exploitation of the vulnerability can lead to cross-origin account linking in violation of WebAuthn goals.
11) Buffer overflow (CVE-ID: CVE-2022-31747)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
